Answer 3

It seems like you've provided a series of equations. Let's solve each of them one by one:

1. -8 = 72 This equation is not correct. There is no solution to this equation because there is no value of x that can make -8 equal to 72.

2. 0.9x = -5.4 To solve for x, divide both sides by 0.9: x = -5.4 / 0.9 x = -6

3. -1.7x = -5.1 To solve for x, divide both sides by -1.7: x = -5.1 / -1.7 x = 3

4. (1/9)x = -8/27 To solve for x, multiply both sides by 9: x = (-8/27) * 9 x = -8/3

5. (5/7)x = 1 To solve for x, multiply both sides by 7/5 (or 1.4): x = 1 * (7/5) x = 7/5 x = 1.4

6. 9x = 20 To solve for x, divide both sides by 9: x = 20 / 9

7. (-2/7)x = 8 To solve for x, multiply both sides by -7/2: x = 8 * (-7/2) x = -28

8. (-3 1/3)x = 10/21 First, convert the mixed number to an improper fraction: (-3 1/3) = (-10/3) Now, solve for x by multiplying both sides by the reciprocal of (-10/3), which is (-3/10): x = (10/21) * (-3/10) x = -3/7

9. 51x = 17 To solve for x, divide both sides by 51: x = 17 / 51 x = 1/3

So, the solutions to these equations are as follows:

1. No solution
2. x = -6
3. x = 3
4. x = -8/3
5. x = 1.4
6. x = 20/9
7. x = -28
8. x = -3/7
9. x = 1/3
